📝 Description

This PR mounts the auth secret token on the runtime so that later during the run method of MPI runtime handler _generate_mpi_job and _configure_pod_template can copy these volumes/volume mounts into the launcher/worker pod template. This allows the mpi pods to authentication with mlrun.

The auth token is already saved as part of the run's spec during the _enrich_run of the ServerSideLauncher.

🛠️ Changes Made

• Add token_name and auth_info to add_secrets_to_spec_before_running() in mpi runtime handler run() method
